Most CCTV systems are set up to record events and store history for a period of _____.

In most CCTV systems, recording events and storing history for a period of 1-2 weeks strikes a balance between the need for a usable amount of footage and the limitations regarding storage capacities. This duration is typically sufficient for most surveillance needs, allowing for the review of recent events without overwhelming storage requirements.

Longer retention periods like 1-2 months or even years may be impractical for standard applications due to the extensive storage costs and the need for higher-capacity recording devices. On the other hand, recording for just 1-2 days may not provide enough historical data for thorough investigations or incident reviews.

Thus, the choice of 1-2 weeks is considered an optimal time frame that accommodates both security monitoring needs and practical storage capabilities, making it the most common configuration in CCTV setups.
